A catheter assembly includes a catheter body and housing attached to the catheter body proximal end, where an actuator lumen extends through the catheter body. A flexible element extends from an actuator member within the housing through the actuator lumen to a deflectable distal end. A first tubular support is provided that is coupled to the flexible element. A second tubular support is coupled with the first tubular support and slidably coupled to the flexible element. In one option, the first tubular support and second tubular support constrain lateral movement of the flexible element when the catheter assembly is operated.

La présente invention concerne un ensemble cathéter comprenant un corps de cathéter et un logement relié à l'extrémité proximale du corps de cathéter, où une lumière d'actionneur s'étend à travers le corps de cathéter. Un élément souple s'étend depuis un élément d'actionneur à l'intérieur du logement, à travers la lumière d'actionneur, jusque vers une extrémité distale orientable. Un premier support tubulaire est relié à l'élément souple. Un second support tubulaire est relié au premier support tubulaire et est relié à l'élément souple de manière à pouvoir coulisser. Dans une variante, le premier support tubulaire et le second support tubulaire limitent un mouvement latéral de l'élément souple lorsque l'ensemble cathéter est actionné.
